a condenser. The position appears to be similar to that in a P-N
junction of semiconductor diodes, Experiments on the activity of
nerve fibres are made by means of artificial excitation with square-
topped pulses of a few msec duration. Fig.2 shows a sketch of a
set-up for studying the electrical phenomena in an axon in the
excited state. The figure also contains an oscillogram of a pulse
which propagates along the fibre and is received by a micro-electrode
placed inside the cell. The pulse amplitude is 100 to 120 mV, its
duration between one and several msec. The parameters of the pulse
do not depend on the excitation force and remain relatively constant
during their passage through the axon, i.e, they propagate Without
attenuation. This is the case only if the excitation current
exceeds the threshold value, which is such that induced e.m.f, from
adjacent excited fibres (Ool to 1 mV) does not lead to erroneous
excilation of a given axon (high noise suppression). As a rough
approximation, the axon communication line can be imagined as a
loop of multi-vibrators interconnected by means of low frequency RC
filters. If one or t~o axon links do not respond, the communication
is not interrupted, since the amplitude of the actuating pulse is

~ to 6 times hiEher than the excitation threshold, so that even if
the signal is received by the third link with considerable attenua-
tion it will still be strong enough to excite it, The transmission
of information to differing organs of the body is effected by
changing the frequency of the pulse sequence along the appropriate
axons an~ ~&so by changing the number of active axons. The muscles
are similarly controlled~ excitation pulses produce contraction of
the muscles~ the intensity of which increases with increasing pulse
frequency, If the axon is in the excited state, the resistance of
the membrane is sharply reduced along an ion flow; the potential
difference on the membrane drops and even changes sign, Following
that9 the particular part of the fibre reverts to the initial state.
For recording bioelectric signal~ tapped off by means of micro-
electrodes9 high gain (103 to 10 ) amplifiers with high input
~esistance (109 to 1011 ohm) and a Wide passband are required. It
is difficult to produce high resistance input stages, However~
this problem can be easily solved by circuits designed for tapping
off doco potentials, Either electrometric tubes or other types of
ordinary tubes are used with operating regimes such as to obtain

minimum grid currents (10-11 to 10-12 &)o To reduce input capacity,
cathode repeaters are used and to reduce the capacitance to ground
of the grid connection the tube, together with the grid input lead,
are screened and the screen iS connected to the cathode. However~
even in this case a capacitance of the order of 2 to 5 pF will
remain. The circuit, Fig.}a, enables obtaining an input capacitance
of Ool pF and a input resistance of 1010 ohms. If it is not
possible to ground one of the micro-electrodes, bipolar leads have
to be used for tapping off the potentials. In this case, the input
stage~ as well as the amplifier, have to be of the balance-
differential type~ a two-stage amplifier with a hath resistance in
the cathode circuits of both tubea (Fig.~b)o For counter phase
input signals, the gain in a stage can be 100 to 1000 times as
large as synphase input signals. For exciting cells~ stimulator
oscillators are used, which produce square-topped voltage pulses of
durations of tens of Bsec to several sec with various pulse
sequences, The output of the stimulator must be insulated from
the ground otherwise it would transmitted by the object and recorded
on the oscillograph, The problem can be solved by transmitting

the pulse through a high frequency transformer, using a 1 to 3 Mc/s
carrier frequency and then to obtain the rectangular stimulator
pulse from the secondary circuit by using a detector circuit. Such
a transformer is usually made without an iron core, which has the
disadvantage of very high leakage. Transformers with ferrite cores
have a Iow leakage but the capacitance betwee]l the windings is
increased, which is undesirable. Yu. H. Lebedev-Krasin
(Radiotekhnika, 1957, No.9) described a special transformer in which
each of the windings is wound on its own toroidal ferrite core and
the coupling between the magnetic fluxes of the cores is effected by
means of a short-circuited turn in the form of two brass cups bolted
together. An electrostatic screen, a brass disc, is placed between
the two cores. The mass of the transformer is grounded. Such a
transformer has a negligible transfer capacitance and is suitable
for operation in the frequency range of 1 kc/s to 1OO Hc/s. For
measuring the electric parameters of nerve and muscle fibres,
electronic circuits are used, particularly a.c.' (10 to 1OO kc/s)
bridges. The high frequencies are chosen because at such frequencies
even higher voltages will not influence the state of the object
under investigation. A new field of biological investigation is

to the antiferromagnetic properties of substances and the associated
anomalies in the electrical properties are similar to those
encountered in ferroelectrics. In view of the fact that ferro-
electrics are being used for memories in computers, it is easy to
understand the major interest of scientists in these effects of
biopolymers in conjunction with problems of hereditary and study of

ABSTRACT: T~e effects of the TiC13:A1Etq ratio on the polymerization of propylene[
was investigated in terms of t~e reactioH taking place, between these two ca-~-~
co~.ponents ~cf. Simon, A., Kollar~ L., and Borocz, L., Monatsh. Chem., vol.
196&, p. 8~2). In general, this reaction reduced the effectiveness of the system
as a catalyst. The extent of this effect was followed by an X-ray determination
of the crystalline TiCi~ content in the catalyst mixture. The X-ray determinations
were performed by the D~partment for Polymer Micromorphology (Polimermikromorfologiai
Osztaly) at the Resesrch Institute for the Plastics Industry. Orig. art. has:

investigate~ 2-component catalysts the most active and stable are I

the authors, a particularly high activity, and stability to aging,
is characteristic of the 2-component syst~-ms which include hydroxides
that exhibit sharply distinct activity in freshly prepared comittion.
~hen the composition of catalysts is made more complex, there is often
observed a change in the order of the reaction, from first to fractional
or zero order. On aging of the catalysts the order of the reaction
changes in the ol~osite direction.

Experimental Data on the Growth of Ice in Irrigation Canals
(Opytnyye dannyye o roste l'da v obvodnitel'nykh kanalakh)~

Meteorologiya i gidrologiya, 1958, Nr 10, pp 40-42 (USSR)

The author investigated the character of growth of the ice
sheet on the Terek-Kuma irrigation system (North Caucasus). He
used 2 channel sections with different water velocities for
5' days from'the time of ice formation. The figuresdetermined
by the author (Table 1) confirmed the indications of references
1 and 2. Assuming the growth intensity of the ice in standing
water (lo) as initial value, he gives formula (1) for the de-
crease of growth intensity Of the ice (Table 3). He also gives
the values of the same intensity (1) for different mean flow
velocities of the water. The most important factor acting upon
the ice sheet is air temperature. The increase in ice thickness
is proportional to the sum of negative air temperatures from
the moment of ice formation. From this, the author derives the
general dependence of the thickness of ice covering (2). Fur-

ther, the formula of the increase in thickness of the ice
covering ()) is given. Table I shows a comparison of experi-
mental data with the values computed according to formula (3)-
Ice grows irregularly in. connection with the cooling of the
water along the canal, and with the ice formation starting
from the terminal sections. Figure 2 gives data for a channel
with a flow velocity of 0.5 m/sec. Thus, it is to be seen that
the thickness of ice covering increases with the gradual heat
loss. On account of observations by the author, a table can be
composed which indicates the ice growth per unit of length of
the camal at different flow velocities under the ice (Table)~.
A formula is given for this dependence. Table 4 gives data on
the increase in ice thickness along canals on account of ac-
tual measurements and computed according to formula (4). The
correct determination of the ice thickness, and the considera-
tion of the increase in ioe thickness, facilitate the selec-
tion of the most rational shape of canal Section and other
parameters. There are 4 tables and 2 Soviet references.

The hydrological main centers of the Terek-Kuma system are
situated a% the rivers Baksan and Ma]ia. In winter theue
constructions meet with great difficulties because of :
sludge ice. Measurements were made to determine the quantity
of sludge ice at the river cross section of the hydroelectric
power stations. Measurements were made with the usual method
by means of a cylindrical instrument designed for the purpose
and a stop watch. The q ~ f(T) diagrams for Malka and Baksan
arc also given here. Sludge ice accumulations at the Baksan
amount to 3-4 times those at the Malka. The formula is written
for the evaluation of the sludge ice discharge at one cross
section of the river. This formula is then rewritten to be
used for the cross section of the Baksan hydroelectric power

ABSTRACT: Using their method of equilibrium condensation described in Vy*sokomolek'u-
lyarny*ye soyedineniya 4, 339, 1962, with chlorodiphenyl in place of ditolylmethane as the
solvent, the authors prepared polyarylates df 4,4'-diphenyldicarboxylic, terephthnlic,
isophthalic, diphenic, fumaric and sebacic acids with phenolphthalein anilido as the base.
The phenolphthalein anilide was prepared by a procedure described by Albert (Berichte der
deutschen chemischen Gesellschaft, 26, 3077, 1893); and ~echnique of interphase polycon-
densation, which was also employed consisted of 1. adding a 0.1 benzene solution of chloro-
anhydride of the dicarboxyllc acid tea0.1 alkaline solution of phenolphthalein anilide,
containing 0.9-1.0% of nekal, 2. thorOUghly mixing for 20 mia, and 3. precipitating tho
polymer with methanol, washing with methanol and hot water and drying in a vacuum at 80C.

ABSTRACT: As the quantity of material in the rotating drum of a mill
alters~ the noise intensity and frequency also alter. A
microphone was installed beside a ball-mill and the noise
e.m.f, was fed to a frequency-meter. When the mill was
overloaded with material the frequency was 350 - ~00 c/s
whereas when it was no~mall� loaded the frequency was
lO00 - llO0 c/s. This relationship between the load on
the mill and the noise-frequency forms the basis of
electro-acoustic regulator type RZM-2: which is described
in this article. This regulator was used to obtain the
relationship between noise-frequency and the level of
material in a ball mill given in Fig 1. It will be seen
that over the working range the change of frequency is

~ith the acoustic regulator shows that the operator was
guided mainly by the frequency. The noise produced by a
mill is an undamped oscillation with a continuous spectrum;
the noise e.m.f, is therefore an aDeriodic time D~nction.
Thus the indication of the frequency ~eter is half the
probable number of times that the noise e.m.f, passes
through zero in one second. The probable number of times
that a random function passes through zero per unit time

The ~uthor then introduces the concept of the 'Rice-

the noise.function e.m.f, per second. A formula is given

second. The height of the vertical lines on the spectro-
gram is proportional to the amplitude of the signal in the
corresponding channel. The frequency scale laid out on
the abscissus of Fig ~ is that charted in Fig ~. When the
spectrogram results are worked out by Rice's formula there
is satisfactory agreement with values of the Rice-frequency
obtained from frequency-meter readings (see Table). It
is considered that, as the load on the mill is increased,
some-of the vibrations of the mill casing are absorbed,
especially the high-frequency vibrations. The spectrograms
given in Fig 6 correspond to an overload on the mill and
it will be noticed that there are tu~'o phases of overload.
In the first the mill cannot take any more material and
the excess is thrown back. If the feeders are then stopped
the Rice-frequency drops appreciably after a few minutes.
This is the second phase of overload. It is evident that
the Rice-frequency actually depends on the fineness of the
material in the mill as well as on the quantity. A ~ick-up,

it is apparent that the frequency meter measures the Rice-

the sig~ml for an autom,~~lc control system determined the
circuit of the electro-acoustic regulator. It comprises
an electro-dynamic microphone, an electronic voltage
amplifier and an electronic frequency converter; a

mathematical analysis shows that the output current is
proportional to the frequency applied, but independent of
the amplitude and wave-shape of the input signal. The
automatic electro-acoustic regulator type RZM-3 is intended
to maintain the load of a ball-mill at a level that gives
the highest output for a given fineness of milling. A block

Priborostroyeniye, 1959, Nr 2, pp 3-6 (USSR)

The factory "Reduktor" of the Leningrad sovnarkhoz produces an
electroaooustic regulator that serves for proper feeding of
the material to be crushed by putting into operation or stop-
ping the feed disk. In the design office "Promstroyavtomatika",
analogue regulators of the type RZM-3 were produced that permit,
under certain conditions, a triple or dual regulation of the
total mill supply without switching off the material infeed
intb the mill.
The regulator HZM-3 consists of a microphone equipment installed
near the mill rollers, of an amplifier and transducer set,
type UPB-1, and of an electric automatic potentiometer, type
EPD-12, consisting of an intermediate relay, type MEU-48 and
of ignition switches, type P-322. The electrodynamic micro-
phone, type MD-35 picks up the noises of the working ball mill

and transforms them into an emf. The amplifier transducer
equipment amplifies this emf on the one hand and tranzforms
it into a medium current on the other, being proportional tc
the oscillation frequency of the picked up
At the output of thi~ set a voltage is generated that is put
on the potentiometer input which indicates and records the
noise frequency. This frequency is a measure for feeding the
mill with material. Simultaneously, the automatic potentiometer
controls the ele~trical motors of the mill rollers, by means
of a contact mechanism over the intermediate relay and the
magnetostarters. In this way, a periodic feeding with material
is achieved.
The scheme of the amplifier transducer set is given. It com-
prises the following elements: valves, type 6N8S and 6N9S,
germanium diodes, type I~-Ts 13.
The difference between the regulators RZM-3 and RZ~-~,
consists only therein that the executing members are of dif-
ferent design according to their ~ty.
For picking up the noise, the electrodynamic microphone, type
MD-35 is used that has a good characteristic within the range
of 50-10000 cycles.

Electroacoustic Regulator fo~ Feeding Ball Mills With Naterial to Be Crushed

The regulation obtained by the regulator is recorded by a
polar recorder. 2 diagrams, one for manual control and one
for automatic regulation show distinctly the advantage of
the latter one.
The experience gained on 220 regulators in 56 cement-works
shows that by means of these apparatus the output may be in-
creased by at least 10-15%. The uniformity of the cement
grain size is about ~wo times better than in the case of
manual control�
The relatively low prime costs of this automatic means and the
results attainable with them are so decisive factors that it
-can be justly expected that these electroacoustic regulators
wi'll find large,distribution in the industry.

~BSTR~CT: This Author Certificate presents a system for combined regulation of two
parameters. The system includes sensing elements for tho parameters being regulated,
comparison units, a control device, slave mechanisms., rogulatin~ elements, and posi-
tion sensing elements of the regulating elements (see Fig. 1). The design optS. mizes
the process of selecting the regulating action as a fw~ction of the character of the
actuating disturbance in the process. Tho position sensing elements of the regulattzg
elements (which act on both regulated parameters simultaneously) are connected to the
input of the control device. The control device is connected to the slave mechanism
which acts only on the regulated parameter characterizing the quality of the product
souEht. The slave mechanisms of the regulating elomen~ acting on both regulated

parameters s~ltaneously and on the regulated parameter characterizL~g the process
efficiency are connected to the common control device through the contacts of three
relays. Each of these relays operates as a function of the combination of the di-
vergence signs of both regulated Parameters from the given values. This operation
is accomplished by Polarized relays connected to the outputs of the comparison units.
